Chubb vs THREE by Berkshire Hathaway: How Do They Compare for Cyber Insurance?

Chubb underwrites Cyber Enterprise Risk Management (Cyber ERM) directly. It covers cyber, privacy and media exposures for organizations of any size that handle sensitive data or run a network or website. ³Company-reported. Cyber Insurance Coverage & Products page, Cyber Enterprise Risk Management section.

THREE presents Cyber as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. ⁷Company-reported. Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant.

The reviewed pages describe Chubb as the carrier but do not name the specific Chubb-group underwriting entity for cyber policies; the issued policy would name the entity. ^4,3Not found in reviewed sources. Both cyber pages as read on 2026-09-23.

The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. ⁶Company-reported. This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy.

Chubb says there are no minimum premiums and premiums scale for all risk sizes, offers Cyber Central and Marketplace quoting for risks under $100 million in revenue, and a customizable large-account cyber risk management solution for organizations over $1 billion in revenue. ³Company-reported. Cyber Insurance Coverage & Products page eligibility and quoting description.

The reviewed product page does not state separate eligibility rules for Cyber; the general quote and advisor route is not proof that a particular business qualifies for it. ^7,5Not publicly disclosed. Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms.

Chubb lists first-party cyber incident response fund, business interruption (with contingent business interruption for outsourced technology providers), digital data recovery, and network extortion; third-party cyber/privacy/network security liability, payment card loss, regulatory proceedings and media liability; and cyber crime coverages (computer fraud, funds transfer fraud, social engineering fraud) available by endorsement. ³Company-reported. Cyber insurance coverage list on the products page; subject to exclusions and the policy as issued.

Chubb offers a Widespread Event Endorsement with separate limits and retentions for systemic cyber events, a Ransomware Encounter Endorsement that lets buyers tailor limits and retentions for ransomware losses, and a Neglected Software Exploit Endorsement that gives a 45-day grace period to patch published vulnerabilities before risk-sharing shifts toward the policyholder. ³Company-reported. Innovative coverage concepts section; endorsement availability depends on underwriting.

THREE's Business Owners Policy page lists Cyber Liability among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. ^7,6Company-reported. Official THREE package marketing for Cyber. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy.

The reviewed pages do not publish specific per-policy limit or retention amounts; Chubb says it can build large insurance tower programs with substantial primary limits for organizations over $1 billion in revenue but gives no figures. ³Not found in reviewed sources. Cyber Insurance Coverage & Products page as read on 2026-09-23.

The reviewed public product page does not state a separate limit or deductible for Cyber; THREE says the quote-specific insurance summary lists limits and deductibles. ^7,6Not publicly disclosed. No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible.

Chubb says cyber policyholders get access to a panel of pre-approved incident response providers, a 24/7 hotline and Cyber Alert app, a Cyber Threat Intelligence Team, a Vulnerability Management Outreach program, and the Chubb Cyber Index for trend and cost data. ⁴Company-reported. Cyber Insurance for Businesses page, Cyber Services and Beyond Risk Transfer sections.

Agents and brokers can quote cyber alone through Cyber Central or bundled with other lines through Chubb Marketplace; multinational programs can be serviced locally in more than 35 countries. ³Company-reported. Cyber Insurance Coverage & Products page quoting section.

THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. ⁵Company-reported. This is the route for the overall THREE product. It does not show whether Cyber will be offered for a particular business or whether a customer can bind that line without an issued policy.

Chubb reports 24/7 incident response availability by hotline or its Cyber Alert app, and publishes an annual Cyber Claims Landscape report analyzing claim frequency, severity and ransomware trends. ⁴Company-reported. Cyber Insurance for Businesses page; claims scenarios and report are company-reported.
